About
I am a Staff Research Engineer at Samsung Research America, where I work in the Advanced MIMO team. I hold a PhD in Electrical Engineering from UT Austin, where I was jointly advised by Prof. Jeffrey Andrews and Prof. François Baccelli. During my PhD, I was part of both the Wireless Networking and Communications Group (WNCG) and the Simons Center for Mathematics of Networks.
I earned my MS in Electrical Engineering from King Abdullah University of Science and Technology (KAUST), where I was advised by Prof. Mohammed-Slim Alouini and worked closely with Prof. Hesham ElSawy.
My research focuses on PHY-layer innovation, mmWave and FR3 systems, and the stochastic modeling of wireless networks. I am a co-inventor on over 20 patents and the author of more than 25 peer-reviewed publications.
